Corvette Exhaust System - B&B Fusion with Quad 4" Round Tips : 2009-2013 C6 for NPP Equipped

Billy Boat has combined the best of the Bullet exhaust with the best technology from the factory to give you the C6 / Z06 Fusion Exhaust NO-DRONE System for your Corvette. Utilizing the same exhaust control valve as the factory system, you get a “Dr. Jekyll” cruising sound, and release the “Mr. Hyde” Bullet Exhaust sound when you want!

How loud is it?
Through our development and customer feedback, we have shortened the muffler, making the “loud” side of the muffler “louder”, which results in a tone similar to the famous Bullet system. In the closed position, the tone would be slightly louder than the standard Route 66 system.

What controls the valves?
The butterfly is controlled by a vacuum valve for non-NPP C6’s Fusion exhausts–which we built and developed completely in house. On the Z06 and the 2008 C6 with the NPP option, this valve is controlled by the ECU. The valve opens based on RPM and throttle position. The problem is the factory exhaust is very quiet, even with the valve open. Our expertise here at B&B is getting the “tone” right for your Corvette, and we think we nailed this one. Even in the closed position, the tone is deeper, louder, and more aggressive. Open the valves, the overall volume and tone increases to the point heads will turn when you drive up.

*Add our conversion kit for Corvette models without factory NPP controls. The kits comes complete with all the wiring, remote switch, vacuum line, vacuum accumulator, and vacuum switch needed for installation. Can only be ordered with Fusion Exhaust Systems.

What’s the difference between our exhaust systems?

– NPP Controlled Bi-Modal…Aggressive when Open, Mild when Closed
Billy Boat Exhaust has designed a Fusion NO-DRONE exhaust for the factory NPP and the non-NPP C6 Corvette. On C6 with the NPP option, the butterfly valve in the exhaust is controlled by the ECU. The valve opens based on RPM and throttle position. Our expertise here at BBE is getting the “tone” right for your Corvette, and we think we nailed this one. Even in the closed position, the tone is deeper, louder, and more aggressive. Open the valves, the overall volume and tone increases to the point heads will turn when you drive up.

– Aggressive Sound at Wide-Open-Throttle, Mild sound at cruise
The Billy Boat Exhaust PRT C6 exhaust system is the latest in resonance control technology from BBE. Completely redesigned and reengineered for the C6, the system is simple in design, though more complex in theory. You can now have a mellow NO-DRONE sound at cruising speeds and a sport note when you’re tearing up the streets. It allows true straight through exhaust passage under aggressive driving conditions, though a mellow sound is emitted at cruising speeds thanks to the unique Purge Chamber. Designed especially for the automatic, paddle shift and cars with headers, this Billy Boat Exhaust PRT system works purely on physics and adrenaline. Increases of 15 hp and 14 ft lbs over stock.

– Aggressive Sound
Billy Boat Exhaust has created a deep, healthy exhaust note at low RPMs with an assertive muscle car roar on acceleration. Not for the weak at heart, the Bullet has quickly become the industry standard for a deep, aggressive muscle car sound on the C6. You can see up to 18 rear wheel horse power and 17 foot pounds of torque from the Bullet. Billy Boat Exhaust’s boldest tip style and configuration insures the C6 will scream ”muscle car”.
